Question

The steps below show the work of a student used to calculate the number of yards in 6.436 meters How can the error in the student's work be corrected?

Answer 1

Given:

1 mile = 1,609 meters

1 mile = 1,760 yards

Asked: Convert 6,436 meters to yards.

Solution:

STEP 1:

`6,436\text{ meters x}\frac{1\text{ mile}}{1,609\text{ meters}}=4\text{ miles}`

STEP 2:

`4\text{ miles x }\frac{1,760\text{ yards}}{1\text{ mile}}=7,040\text{ yards}`

NOTE: The error the student made is in the operation. The student used division when multiplication is supposed to be the operation.

STEP 3: 7,040 yards
